‘And so it was, when God destroyed the cities of the plain, that God remembered Abraham and sent Lot out of the midst of the overthrow, when He overthrew the cities in which Lot dwelt.'
Throughout the whole account the writer has spoken of Yahweh, for it has had continually in mind the deliverance of Lot who has a part in the covenant because of his relationship with Abraham and his faith in Yahweh, and the writer wants us to know it. But in this solemn summary the writer refers to ‘God'. He is now viewing the disaster as a whole from a world viewpoint, with emphasis on the disaster. It was God, the judge of all, who spared Lot, and He did it for Abraham's sake.
“God remembered Abraham”. In all His dealings God remembers those who are faithful to Him, and His actions ever have them in mind. In the end it was because of His love for Abraham that Lot was delivered. Lot owed Abraham more than he ever knew. But the use of the name ‘God' suggests that especially in mind is Abraham's intercession before ‘the Judge of all the earth'. We are assured that the Judge bore in mind his pleas and his arguments and acted accordingly.
